Moreover, bicycling has become a very popular competitive sport for both amateurs and professionals. Whether the bicycle is used for recreation, transportation or competition, the bicycle industry is constantly improving the various components of the bicycle.
  • One component that has been extensively redesigned is the bicycle bottom bracket that is often called a bottom bracket.
  • Japanese Laid-Open Patent Publication No. 2004-249770 discloses a conventional bottom bracket that is mounted on a hanger part of a bicycle.
